For anyone that doesn't bother reading the whole neogaf thread, some more info came out. PS4 COD ghosts took a month to get running and as at 90FPS. The XBONE version took 4 months and was at 15FPS. A Japanese dev (not SE) experienced similar.

Probably exaggerated numbers but still revealing.

what thread is it in?

The one Penello posted in. Here's a link to the actual post about COD http://www.neogaf.com/forum/showpost.php?p=81321425&postcount=422

Oh wow a second-hand anecdote posted on a forum. Seems credible.
